## Documentation

# Deploy and Host Coral Talk on Railway

**Coral Talk** is an open-source community discussion and commenting platform originally built to power large-scale publisher communities. It provides real-time conversations, moderation tools, user authentication, and extensible APIs, making it suitable for media sites, blogs, and content-driven platforms that want high-quality engagement.

## About Hosting Coral Talk

Hosting Coral Talk involves running the Coral application alongside its required data services. Coral relies on **MongoDB** for primary data storage and **Redis** for caching, queues, and real-time functionality. On Railway, this setup maps cleanly to a multi-service deployment: one application service plus managed MongoDB and Redis services. Environment variables are used to wire services together, while Railway handles networking, scaling, restarts, and secrets management. No manual infrastructure provisioning or VM management is required.

## Common Use Cases

- Powering comments and discussions on news or media websites  
- Adding moderated community conversations to blogs or content platforms  
- Running a standalone discussion community with custom authentication  
- Integrating commenting via Coral’s APIs into existing products  

## Dependencies for Coral Talk Hosting

- **MongoDB** – primary datastore for users, comments, and configuration  
- **Redis** – caching, background jobs, and real-time features  

### Deployment Dependencies

- Official Coral repository: https://github.com/coralproject/talk  
- MongoDB (Railway managed service or external)  
- Redis (Railway managed service or external)  

### Implementation Details 

- The Coral app is typically deployed as a single service.
- Required connection strings (e.g. `MONGODB_URI`, `REDIS_URL`) are provided via environment variables.
- Persistent storage is handled entirely by MongoDB; no application volume is required unless custom uploads are enabled.
